Everyone knows: wars are getting worse, more civilians are dying, and peacemaking achieves nothing, right? Wrong. Despite all the bad-news headlines, peacekeeping is working. Fewer wars are starting, more are ending, and those that remain are smaller and more localized. But peace doesn't just happen; it needs to be put into effect. Moreover, understanding the global decline in armed conflict is crucial as America shifts to an era of lower military budgets and operations. Preeminent scholar of international relations, Joshua Goldstein, definitively illustrates how decades of effort by humanitarian aid agencies, popular movements - and especially the United Nations - have made a measurable difference in reducing violence in our times. Goldstein shows how we can continue building on these inspiring achievements to keep winning the war on war. This updated and revised edition includes more information on a post-9-11 world, and is a perfect compendium for those wishing to learn more about the United States' armed conflicts in Iraq and Afghanistan.
